[Fot] variation in Timken carrier bearing width?

Yes!
I have run into that on several occasions but can't remember the Timken numbers, nor do I have a technical explanation.

Subject: [Fot] variation in Timken carrier bearing width?



Has anyone else noticed rather large variation in carrier bearing width's when rebuilding a spitfire differential?  The one I'm building right now, I've replaced what I suspect are the original bearings (Timken England) with brand new Timken USA bearings.  In order to reach the required .004" preload, it will require .012" LESS total shim than what was in there originally.  That seems like a big difference with the only variable being new bearings.  I'm using the same housing, same carrier, the bearings visually look to be fully pressed home.  Anyone else experience this?


Thanks,



Jason Sukey
